The topic of international cooperation between national movements before the end of World War I (WWI) has still not received sufficient scholarly attention. It is common for national historiographies to concentrate on the case of their own nation. When it comes to international relations, however, connections with neighboring nations and national movements - chief adversaries in the achievement of national goals - are usually prioritized. Nevertheless, even before and especially during the war there was a vibrant scene where non-dominant nationalities could practice international diplomacy, conduct discussions, share experiences, build coalitions, and so on. This article explores one of such examples of international relations conducted between the representatives of two nations - the Catalans and the Lithuanians. They came in contact before the war at the Paris-based Union des Nationalités (the Union of Nationalities), an organization that was designed to unite and support non-dominant national movements. Despite being located on the opposite sides of Europe and having no apparent direct connections, the Lithuanians and the Catalans established common ground for cooperation, which especially peaked during WWI.
